The software addresses computational fluid dynamics, the flow behavior of gases and liquids.&nbsp;<\/p>\n<p>Using data from the 2022 Artemis I launch, researchers at NASA\u2019s Ames Research Center in California\u2019s Silicon Valley used LAVA to simulate complex interactions between the rocket plume and a system that pumps water to suppress sound during launch. The system protects the rocket and other equipment from potentially damaging sound waves.&nbsp;<\/p>\n<p>Comparing simulations with and without the sound suppression system activated revealed that the water effectively reduces pressure waves from sound, but exhaust gases from the rocket could also redirect water, causing significant pressure increases in certain areas of the launchpad. \u202f&nbsp;<\/p>\n<p>The LAVA simulations improved NASA\u2019s understanding of the plume interaction with the Artemis&nbsp;<a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/ml-ml2-comparison-infographic.pdf?emrc=69bd63576818c\"  rel=\"noreferrer noopener\">mobile launcher<\/a>&nbsp;platform.

impact on a mission, which\u00a0is\u00a0why NASA used advanced simulations to provide\u00a0the best possible launch conditions\u00a0for\u00a0the\u00a0Artemis II\u00a0test flight around the Moon.\u00a0 To better understand the\u00a0Artemis\u00a0Space Launch System (SLS) rocket\u2019s flight environment, engineers turned\u00a0to a NASA-developed tool called the Launch, Ascent, and\u00a0Vehicle Aerodynamics
